The body lay crumpled beneath the grand piano's silent shadow. Detective Mara Voss knelt beside it, her breath held tight. A single crimson rose rested on the dead man's chest. Rain streaked the library windows like tears against the glass. Nobody else was in the room when the clock struck. The dead man's name was Alistair Finch, a wealthy philanthropist. His final dinner guests waited downstairs, unaware of the horror. One of them was lying about where they had been. Mara picked up the rose and found a thorn beneath. A small note was pinned inside his jacket's silk lining. Its message read: You were never supposed to know it. Then the lights went out, and someone screamed from downstairs.
